Do marketplace sales count toward the threshold? Sources disagree
This is one of the jurisdictions where published sources do not agree, so StateWise does not pick one.
Sources disagree on Massachusetts. The Sales Tax Institute Economic Nexus State Guide, the source StateWise seeds from, records marketplace-facilitated sales as excluded from the seller's own threshold. Vendor guides describe that exclusion as conditional and do not agree on the condition; StateWise does not cite those, because they sell competing services and disagree with each other on exactly this column, so no second source is named here. StateWise does not pick between the readings: both are shown in full, each with its own number and its own verdict. The Massachusetts Department of Revenue is the only authority that can settle it. Ask them before you register, and before you decide not to.
The app renders both readings side by side and names the disagreement wherever Massachusetts appears. Resolving it silently in either direction is the thing a monitoring tool must not do: reading it one way can understate exposure, and reading it the other can lead to registering somewhere it was never owed, which buys permanent filing obligations in a state with little sales in it.
What "measured over" is doing
A threshold is a number and a period, and the period is the part most charts omit. Massachusetts measures over the previous or the current calendar year, whichever triggers first. Two sellers with identical annual sales can sit on opposite sides of this line because their sales fall differently inside that window.

What this page does not tell you
- Whether what you sell is taxable in Massachusetts.
- Anything about home-rule local taxes, which are outside this tool.
- What happens to an obligation after sales fall back below a threshold.
- Any deadline. Crossing a threshold is the point at which a state expects a seller to look into registering, and that decision has lasting consequences in both directions.
